100-things meme, geologists edition

In der englischsprachigen Blogosphäre geistert je seit geraumer Zeit das 100-things meme herum. jetzt gibt es auch eine "geologists edition". Bleiben wir also bei der englischen Version.

Things I have personally seen or done are bold and my comments are in italics

1. See an erupting volcano (Stromboli, Italy. very impressive!)

2. See a glacier ( Ortler group, Italy)

3. See an active geyser such as those in Yellowstone, New Zealand or Iceland

4. Visit the Cretaceous/Tertiary (KT) Boundary. Possible locations include Gubbio, Italy, Stevns Klint, Denmark, the Red Deer River Valley near Drumheller, Alberta. (Stevns Klint, Denmark)

5. Observe (from a safe distance) a river whose discharge is above bankful stage

6. Explore a limestone cave. Try Carlsbad Caverns in New Mexico, Lehman Caves in Great Basin National Park, or the caves of Kentucky, Tennessee, Alabama, and Georgia.
( non of the mentioned, but the caves in Bavaria (Oberfranken) are also very nice. Especialy the not touristic ones wher you have to feel like a real exploerer like the Zoolithen Höhle)

7. Tour an open pit mine, such as those in Butte, Montana, Bingham Canyon, Utah, Summitville, Colorado, Globe or Morenci, Arizona, or Chuquicamata, Chile. (The brown coal mines in the Lausitz with the big conveyor bridges)

8. Explore a subsurface mine. (several. Historical mines in the hercynian mountains like Roter Bär etc, Rammelsberg and in Uganda the Kilembe Mines for example)

9. See an ophiolite, such as the ophiolite complex in Oman or the Troodos complex on the Island Cyprus. (The Ballantrae Ophiolite, Scotland)

10. An anorthosite complex, such as those in Labrador, the Adirondacks, and Niger. (Only a smaller Anorthosite at Gorm Loch, Scotland, does that count?)

11. A slot canyon. Many of these amazing canyons are less than 3 feet wide and over 100 feet deep. They reside on the Colorado Plateau.

12. Varves, whether you see the type section in Sweden or examples elsewhere

13. An exfoliation dome, such as those in the Sierra Nevada.

14. A layered igneous intrusion, such as the Stillwater complex in Montana or the Skaergaard Complex in Eastern Greenland. (Bin Quarry, Scotland, also at Huntley Castle, Scotland)

15. Coastlines along the leading and trailing edge of a tectonic plate.

16. A gingko tree, which is the lone survivor of an ancient group of softwoods that covered much of the Northern Hemisphere in the Mesozoic. (in my own backyard)

17. Living and fossilized stromatolites. (only fossilized ones at Lake Manyara, Tanzania)

18. A field of glacial erratics. (Finland, Northern Germany etc.)

21. A fjord. (several in Scandinavia)

22. A recently formed fault scarp.

23. A megabreccia.

24. An actively accreting river delta. (The river nile is actually not accreting any more, I guess)

25. A natural bridge. (Songwe River, Tanzania)

26. A large sinkhole. (Ponore in Franken, bavaria)

27. A glacial outwash plain. (Sander in Northern germany, pleistocene, as well as at the Ortler Glacier, Italy)
